Trevor Williams Is Staging a Comeback
This is Chet’s first piece as a FanGraphs contributor. He believes data is the most compelling storyteller and loves using analytics to attempt to demystify the game of baseball. He previously covered the Colorado Rockies for Purple Row. A graduate of Georgia Tech, he had the opportunity to participate in Danny Hall’s walk-on tryout in 2003, though he apparently failed to blow the legendary coach away with his 76 mph fastball. Chet lives in Lakewood, Colorado with his wife and two children, all of whom tolerate way too much baseball talk at the dinner table.
Trevor Williams headed into spring training at a pivotal moment in his career. Following two solid seasons of work in the Pirates’ rotation, he experienced a somewhat delayed sophomore slump in 2019. His performance declined significantly. He finished the season with an ERA of 5.38 and a FIP of 5.12 both more than a run higher than the average from the previous two seasons. His campaign to bounce back in 2020 never took off and he ended up on the wrong side of the small sample coin flip, ending the year with a 6.30 FIP and -0.4 WAR, career lows. He was designated for assignment in November.
Fresh off trading their former ace, Yu Darvish, the Chicago Cubs scooped Williams up on a low-risk, one-year deal for $2.5 million. From the Cubs’ point of view, the upside is clear. While Williams has had an awful go of it recently, he is only 28 years old and was once a capable fixture in a major league rotation. Williams (in the parlance of our times) shoved throughout spring training and earned himself the position as No. 4 starter in the Cubs’ rotation, but the question remains as to whether or not he can perform as he once did in 2017 and ’18.
Let’s rewind the tape a bit. Williams had a brief cup of coffee (one start and 12.2 total innings) in 2016 before starting the ’17 season in Pittsburgh’s bullpen. In the season lead-up, our own Eric Longenhagen had this to say of Williams:
“A lead-armed sinkerballer who dominated the International League with a low-90s fastball/sinker combo that he’d run up to 94, Williams made too many mistakes in the zone with that fastball and below-average changeup in his few big-league innings. He has an above-average slider and that pitch, down and in, is his best weapon against lefties. The command is going to need to come here if Williams is going to be more than a fifth- or sixth-starter type of arm.”
